我正在尝试在任何地方同步python教程上的数据库。当我这样做时，我已经删除了所有内容并重新启动了几次教程：

python ./manage.py syncdb

03:23 ~ $ cd mysite
03:23 ~/mysite $ ls
__init__.py __init__.pyc manage.py media settings.py settings.pyc static testdb urls.py urls.pyc
03:23 ~/mysite $ python ./manage.py syncdb
Traceback (most recent call last):
File "./manage.py", line 14, in <module>
execute_manager(settings)
File "/usr/local/lib/python2.7/dist-packages/django/core/management/__init__.py", line 438, in execute_manager
utility.execute()

有几件事可能会导致此问题：

  1. 如果您在 settings.py 中使用 sqlite 文件的相对路径，请尝试将其更改为绝对路径：

    而不是~/project/mydata.db使用/home/user/project/mydata.db.

  2. 如果您没有正确设置权限，则可能会在写入文件时遇到问题。试试这个：

    sudo python manage.py syncdb

    如果可行，这是您需要解决的简单权限错误。

  3. 项目的目录文件名和数据库文件之间可能存在名称冲突。如果 settings.py 中的数据库名称与项目名称相同，请尝试.db在文件名中添加 a：

    IE

    项目名：test

    数据库名称test.db
